植物受到昆虫取食后,能在受损伤组织产生一系列的生理变化,从而提高植物的抗虫能力。在上世纪70年代,科学家就发现,除了被取食的叶片或组织,未被损伤的其它叶片或组织也能够产生抗虫响应,被称为系统性响应,说明有一种或多种信号从被昆虫取食的叶片或者组织移动到植物的其它部位,诱导抗虫响应。然而,这个可移动信号是什么,是由哪些基因调控的仍然不清楚。中国科学院昆明植物研究所吴建
Plants fed insects, can produce a series of physiological changes in the damaged tissue, thereby enhancing the plant’s insect resistance. In the 1970s, scientists discovered that other leaves or tissues that were not damaged, other than the leaves or tissues that were eaten, were also able to produce insect-resistant responses, called systemic responses, indicating one or more signals from the Insect-fed leaves or tissues move to other parts of the plant, inducing insect resistance. However, it is unclear what genes are affected by this moveable signal. Kunming Institute of Botany, Chinese Academy of Sciences Wu Jian
